The present invention relates to an aqueous dispersion, comprising or consisting of A) at least one cyclic olefin copolymer, B) at least one surfactant; optionally C) at least one adhesion promoter; optionally D) at least one film-forming resin; optionally E) at least one additive; and F) water. Additionally, the invention relates to methods of manufacturing the aqueous dispersion, to an article, which comprises at least one substrate and at least one coating layer obtained from the aqueous dispersion and applied onto the substrate; and to methods of improving MVTR of a substrate.

Water based dispersion to make coatings with increased MVTR barrier properties

The present invention relates to a method for providing electrically insulating and anti-corrosive coatings on electrical steel strip by using a phosphate-free aqueous dispersion. Furthermore, the invention relates to such an aqueous dispersion which is particularly suitable for providing electrically insulating and anti-corrosive coatings on electrical steel strip. The aqueous dispersion of the present invention is substantially free of phosphates and organic compounds and comprises silicates dissolved in water as an inorganic binder which forms the coating, and a mixture of oxide pigments of the elements titanium and aluminum. The subject matter of the invention also comprises a laminated electrical steel strip which is made from the electrical steel strip produced in the method according to the invention or from electrical steel strip coated with an aqueous dispersion according to the invention.

Chromium- and phosphate-free coating for electrically insulating an electric strip

The present invention relates to a conductive coating composition comprising a polyolefin copolymer resin comprising an olefin monomer and acrylic acid comonomer or (meth)acrylic acid comonomer, a plurality of anisotropic nanoparticles and a solvent.

Conductive transparent coating for rigid and flexible substrates

The present invention relates to hydrophilic coatings for heat exchangers, and methods and compositions for depositing such coatings comprising applying a composition comprising at least one curable polyvinyl alcohol and at least one wetting agent to a surface of a metal substrate and curing the composition on the surface of the metal substrate.

Hydrophilic coating for heat exchangers

The present invention relates to a water-based can inner coating based on a copolymer or a copolymer blend of at least one aliphatic and acyclic alkene having at least one &#x3b1;,&#x3b2;-unsaturated carboxylic acid in water-dispersed form, wherein the can inner coating contains a water-soluble curing agent selected from inorganic compounds of the elements Zr and/or Ti, so that the need for using organic hardener systems can be largely avoided. The present invention further relates to a method for the internal coating of tin cans or aluminum cans, in which the previously mentioned can inner coating is directly applied to the metallic inner surfaces of the cans and cured without any need to carry out a conversion treatment for improving coating adhesion of the inner surfaces of the cans.

Highly curable coating formulation for the inner surfaces of cans

The present invention relates to a method for manufacturing coated can lids from aluminum strip, and is based on the finding that flexible, easily formable coatings having high abrasion resistance result from the use of water-based lacquers containing a copolymer or a copolymer mixture of at least one aliphatic, acyclic alkene with at least one &#x3b1;,&#x3b2;-unsaturated carboxylic acid in water-dispersed form, and a curing system. In a preferred embodiment of the method, the application of a primer coating can be dispensed with entirely when water-soluble compounds of the elements Zr and/or Ti in the lacquer are used as the curing system.

Method for manufacturing coated can lids

The invention relates to an aqueous, chromium-free and curable corrosion protection agent for the first coating of metal surfaces, said agent containing at least one organic polymer or copolymer of at least partially acylated vinyl amines, for improving the properties of adhesion of the cured first coating to the metallic surface and to further organic coatings. The invention also relates to a method for producing a first coating comprising the agent according to the invention, and for applying further organic coatings, in particular those based on polyurethane resins and/or based on isocyanates and diols or polyols, and to a metal strip produced in this way or a metal sheet cut off same, which can optionally be shaped.
